General questions 1. establishes the minimum requirements for the protection of workers against the risks arising from or can cause electromagnetic fields exposure time (all known direct biophysical and indirect effects). 2. the rules shall have the following terms: 2.1 electromagnetic fields, static electric, static magnetic and time variable electric, magnetic and electromagnetic fields, which does not exceed 300 GHz frequency; 2.2. the direct biophysical impact – effect on the human body that directly causes the electromagnetic field in which it is situated, including: 2.2.1. impact-tissue thermal heating in tissue caused by the absorption of energy from electromagnetic fields; 2.2.2. the non-thermal effects, muscle, nerves, or a sensory irritation; 2.2.3. arms and legs induced current; 2.3. the indirect impact – the impact caused by the electromagnetic field, which can cause such a security or health risk: 2.3.1. electronic medical equipment and devices, including pacemakers and other implanted devices or on the body to wear medical devices, interference; 2.3.2. the mechanical shock risk of feromagnētisk objects in static magnetic fields; 2.3.3. elektroeksplozīv devices (detonators); 2.3.4. fires and explosions resulting from ignition of flammable materials by sparks caused by induced fields, contact or dzirksteļizlād; 2.3.5. overhead; 2.4. the exposure limit values (ER)-electromagnetic field exposure limits based on their impact on human health, and which are subject to the workers who are exposed to electromagnetic fields are protected against the harmful effects on health. The limit values referred to in these provisions apply only to the scientifically established link between the direct biophysical effects and short term electromagnetic field exposure. The meaning of these rules: 2.4.1. exposure limit value in relation to the effects on health are the limit values that exceed the workers could be exposed to the harmful effects on health (thermal to heat or to the nerve and muscle tissue stimulation); 2.4.2. the exposure limit value in relation to the effects on sensory organs are the limit values that exceed the employees may experience temporary perceptual disorders and minor changes in brain function; 2.5. the exposure action value (DV) – the action levels set out to simplify the process of attesting to compliance with the relevant exposure limit values referred to in these provisions or protection and preventive measures. Exposure action value may be the following: 2.5.1. for electric fields – "low transaction value" and "high value" activities that relate to the specific protection provided for in these rules or to preventive measures; 2.5.2. in relation to the magnetic fields – "low value" activities relating to the impact of exposure to sensory organs and the action value of "high", which refers to the exposure of health effects; 2.6. a special risk group, workers under 18 years of age, pregnant women, persons whose body is active or passive implanted medical device (pacemaker, metal prostheses), as well as the person who uses the body wearable medical device (insulin pumps); 2.7. the electric field strength (E), physical size, possessing vectorial nature. It is expressed in volts per meter (V/m). A distinction should be made between environmental electric field from the electric field (in situ), caused by the electric field of the environment; 2.8. the arms and legs induced current (IL) – current in amperes (A) employed in the hand or leg it in effect to magnetic field frequency range of 10 MHz to 110 MHz, tapping the electromagnetic field or the subject of capacitive power that induced the exposed body; 2.9. contact (IC)-current in amperes (A), which occurs when employees faced with an object in the electromagnetic field. The stationary contact occurs when the electromagnetic field workers sustained contact with the object.
